BICYCLE-STAND.

SPECIFICATION forming part of Letters Patent No. 431,740, dated July 8, 1890.

Application filed April 28, 1890, $erial No. 349,863. (No model.)

My invention relates to the class of devices that are used for the purpose of retaining a bicycle in an upright position for storage, and also that are adapted for use as a means for enabling a rider to exercise on the machine under practically the same conditions as in normal use.

My invention consists in the combination of the base, clamps, braces, and supporting parts making up the device as a whole, as more particularly hereinafter described, and pointed out in the claims. I

Referring to the drawings, Figure 1 is a perspective View of the device in position for use as a trainer. Fig. 2 is a detail view of one of the braces. Fig. 3 is a detail view illustrating the method of using the braces and showing some of the parts in vertical section.

In the accompanying drawings, the letter a denotes a bicycle of the safety type in which the rear wheel is geared up with the crank, usually by a flexible connection, and forms the driving-wheel that more immediately supports the weight of the person using the wheel. I

1) denotes the driving-wheel; c, a substantially horizontal part of the frame 0 near the axle b of the driving-wheel. The stand d is preferably of a cruciform shape, is made, preferably, of wood, with the arms cl and the up-- right bracket cl", that is secured to the front end of the frame, and is forked to embrace the felly of the forward wheel 6 at a point about midway of its height. The wheel 6 rests in sockets in the frame, and braces f, terminating at the upper end in=the clamp f, are pivoted to the outer ends of the arms (1' and arranged to be clamped securely to the frame of the machine at a point preferably just below the handle-bar.

Directlybelow the axis of the driving-wheel a roller 9 is journaled in suitable bearings g, secured to the frame d. This friction or brake roller g is provided with a peripheral groove g, and is preferably made of metal cast to shape, the shaft being made of a cylindrical piece of steel secured to the body of the wheel in the process of casting.

The braces h each consist of a rod of metal, preferably iron or steel, having the point h at the lower end and terminating at the upper end in a fork h. This fork in the head of the brace is adapted to engage the part of the frame 0' immediately adjacent to the axle '1) of the driving-Wheel in such manner as to .prevent the braces from slipping, while the lower pointed ends of each of the braces is adapted to be driven into the fioor upon opposite sides of the frame. These braces are simple and cheap in construction and are used to regulate or adjust the vertical position of the driving-wheel with respect to the friction-roller g by regulating the distance out from the center of the frame at which the braces enter the floor on which the frame rests. When the pointed ends of the braces are in the positions illustrated in Fig. 1 of the drawings, they serve to hold the drivingwheels against side swaying and permit the larger part of the weight of the rider to rest normally on the roller g; but by bringing the pointed ends of'the braces nearer together the wheel is lifted and pressure is removed from the friction-roller g, so that but little per end in a clamp adapted to be secured to the frame of a wheel, an upright support for the front wheel secured to the front end of the stand, a pressure-roller j ournaled in bearings near the rear end of the stand, and braces having pointed lower ends and a forked head IOO adapted to engage the frame of a bicycle adadapted to be attached to the opposite sides jacent tothe axisof thedriVing-Wheel, all sub- 01: the frame near the aXle of the driving- 10 stantially as described.
